External auditory canal stent for endoscopic ear surgery

Abstract

The invention belongs to the technical field of surgical instruments, and in particular relates to an external auditory canal stent for an endoscopic ear surgery. The stent includes an upper arc platefor supporting the upper half of the external auditory canal and a lower arc plate for supporting the lower half of the external auditory canal. The upper arc plate and the lower arc plate are matched to open the external auditory canal of a patient. The hole cavity defined by the upper arc plate and the lower arc plate constitute an operation channel for a surgical instrument and an endoscope toextend. A positioning rod extends vertically from the inner arc surface of at least one of the upper arc plate and the lower arc plate. A spherical rotating head or a metal shaping pipe is fixed on the positioning rod, and the rotating end of the spherical rotating head or the other end of the metal shaping pipe opposite to the fixed end of the positioning rod is provided with a hoop hole or a fixing bayonet for fixing the endoscope. The stent reduces the labor intensity of a surgeon while ensuring the clarity of the surgical field, and ensures the efficient convenient operation of the surgical process.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and in particular relates to an external auditory canal bracket for endoscopic surgery. Background technique [0002] Ear endoscopic surgery requires the surgeon to hold the ear endoscope in the left hand and surgical instruments in the right hand, and insert the endoscope and surgical instruments into the ear through the patient's external auditory canal in order to perform surgical treatment on the patient. During the actual operation, because the surgeon needs to hold the endoscope with his left hand for a long time, and constantly adjust the direction of the endoscope according to the situation, the hand will inevitably shake due to fatigue, resulting in unclear surgical field of vision and affecting the surgeon. The therapeutic effect on patients, and greatly increased the labor intensity of surgeons. In addition, since the surgeon needs to hold the otoscope with one hand, he o...

Problems solved by technology

During the actual operation, because the surgeon needs to hold the endoscope with his left hand for a long time, and constantly adjust the direction of the endoscope according to the situation, the hand will inevitably shake due to fatigue, resulting in unclear surgical field of view and affecting the surgeon. The therapeutic effect on patients, and greatly increased the labor intensity of surgeons

In addition, since the surgeon needs to hold the otoscope with one hand, he only has one hand to perform other surgical operations, which is extremely inconvenient to use

When encountering a situation that requires two-handed operation, the surgeon must rely on the assistant to hold the mirror, and the communication and coordination between the doctor and the assistant is also a problem, which brings many interference factors to the actual operation
